A man hasn't come in 72 hours, he gets hand from a women/man who has a cold, as he is about to cum he uses a feather or such item like that to make the man/women sneeze and if timing is right, the big cum shot and the big sneeze should clash in the air. hence clash of the titans
Zach has a cold and is give sam hand, zach sneezes when sam cums and both the cum and mucus collide in mid air. They would then have completed clash of the titans.
